  • Description: Microwave imaging has become a popular research issue in recent decades as a result of its several benefits over traditional imaging technologies. To analyze biological tissues in depth, a microwave imaging instrument is employed. The test determines the presence and location of morphological alterations in specific biological tissues. Ultrawideband (UWB) microwave imaging is a new technique that produces improved results while avoiding the use of ionizing radiation. Antennas play a critical part in these systems, and as a result, antenna optimization has become a hot topic due to the device's proximity to the human body. Recent research has revealed a number of initiatives to improve the electromagnetic sensors employed in these systems, whether as single or array components. In this article, the development of a compact ultrawideband (UWB) antenna functioning in the frequency range of 3.25–14.63 GHz is proposed. The reported antenna comprises of a rectangular patch and a modified ground plane "etched on an FR4" substrate excited by a 50 Ω feed line. The overall dimension of the antenna is 0.44 λ 0 × 0.38 λ 0 × 0.02 λ 0 . The proposed antenna has been fabricated on FR-4 substrate. Measured and simulated results are in good agreement. The proposed antenna is compact and displays good radiation characteristics along with good gain.
